Bazı çocuklar uzun süreli konuşma terapisi almayı gerektiren konuşma bozukluklarına sahip olabilmektedir. Dil ve konuşma terapistliğinin Türkiye'de yeni gelişen bir alan olması sebebiyle bu konuda yapılmış çok az araştırma vardır. Bu çalışmada, Golding-Kushner'ın önerdiği damak yarıklı çocuklarda uygulanabilecek bir sesletim terapi programının, Türkçe konuşan çocuklar üzerindeki etkililiği değerlendirilmiştir. Bu amaç için tek denekli araştırma modellerinden yoklama evreli çoklu yoklama modeli kullanılmış ve davranış değiştirme programının etkililiği, birden fazla seste (davranışta) değerlendirilmiştir. Terapi programının etkililiğini test etmek için iki denek seçilmiştir. Deneklerden birinin sesletim, diğerinin sesbilgisel bozukluğu bulunmaktadır. Her iki denek de beş yaşındadır ve sadece yumuşak damak yarıklığı tanısı almışlardır. Araştırmanın ve sonuçların güvenirliliği için gözlemciler arası güvenirlik ve uygulama güvenirliliği verileri toplanmış, araştırma sonuçları grafiklerle gösterilmiştir. Çalışma sonucunda sesletim bozukluğu olan denekte tüm seslerde; sesbilgisel bozukluğu olan denekte ise sadece /k/ sesinde amaca ulaşıldığı görülmüştür

Electrostatically driven fog collection using space charge injection
No full textFog collection can be a sustainable solution to water scarcity in many regions around the world. Most proposed collectors are meshes that rely on inertial collision for droplet capture and are inherently limited by aerodynamics. We propose a new approach in which we introduce electrical forces that can overcome aerodynamic drag forces. Using an ion emitter, we introduce a space charge into the fog to impart a net charge to the incoming fog droplets and direct them toward a collector using an imposed electric field. We experimentally measure the collection efficiency on single wires, two-wire systems, and meshes and propose a physical model to quantify it. We identify the regimes of optimal collection and provide insights into designing effective fog harvesting systems.Massachusetts Institute of Technology. Tata Center for Technology and Desig

Pr3+:BaY2F8 crystal nanoparticles (24 nm) produced by high-energy ball milling: Spectroscopic characterization and comparison with bulk properties
No full textNanocrystals (NC) of Pr3+:BaY2F8 with average
diameter of 24 nm have been successfully prepared by highenergy
ball milling. The method is versatile, easily scalable, and
does not require the use of surfactants or catalysts. NC were
prepared starting from high quality single crystal pieces, and
their spectroscopic features are analyzed and compared with
those of a single bulk crystal. Under 445 nm excitation, we
recorded the 10 K and room temperature emission spectra of
the two samples. The spectra show the same peak positions
and width, and this means that the milling process does not
introduce substantial modifications to the crystal structure.
Besides, there are strong differences in the relative intensity of
the lines emitted toward different lower lying levels in the two
samples. In particular, the high-energy transitions seem to be hyper intense in the NC with respect to the bulk sample. On the
contrary, the emission lines that end at excited levels are less intense in the NC. In addition, the time evolution of the 3P0 decay
shows striking differences between the nanosized materials and the bulk sample. Despite the exponential decay of the latter
luminescence (τ = 43 μs), NC possess a strong nonlinear component with a lifetime much shorter than in the bulk. Calculations
show that nearly 89% of the excited ions contribute to the short-time decay, which is attributed to ions residing near the NC
surface

Improving the Accuracy of Industrial Robots by offline Compensation of Joints Errors
No full textThe use of industrial robots in many fields of industry like prototyping, pre-machining and end milling is limited because of their poor accuracy. Robot joints are mainly responsible for this poor accuracy. The flexibility of robots joints and the kinematic errors in the transmission systems produce a significant error of position in the level of the end-effector. This paper presents these two types of joint errors. Identification methods are presented with experimental validation on a 6 axes industrial robot, STAUBLI RX 170 BH. An offline correction method used to improve the accuracy of this robot is validated experimentally
Feedrate planning for machining with industrial six-axis robots
No full textThe authors want to thank Stäubli for providing the necessary information of the controller, Dynalog for its contribution to the experimental validations and X. Helle for its material contributions.Nowadays, the adaptation of industrial robots to carry out high-speed machining operations is strongly required by the manufacturing industry. This new technology machining process demands the improvement of the overall performances of robots to achieve an accuracy level close to that realized by machine-tools. This paper presents a method of trajectory planning adapted for continuous machining by robot. The methodology used is based on a parametric interpolation of the geometry in the operational space. FIR filters properties are exploited to generate the tool feedrate with limited jerk. This planning method is validated experimentally on an industrial robot
Large paleoearthquake timing and displacement near Damak in eastern Nepal on the Himalayan Frontal Thrust
No full textAn excavation across the Himalayan Frontal Thrust near Damak in eastern Nepal shows displacement on a fault plane dipping similar to 22 degrees has produced vertical separation across a scarp equal to 5.5m. Stratigraphic, structural, geometrical, and radiocarbon observations are interpreted to indicate that the displacement is the result of a single earthquake of 11.33.5m of dip-slip displacement that occurred 1146-1256A.D. Empirical scaling laws indicate that thrust earthquakes characterized by average displacements of this size may produce rupture lengths of 450 to >800km and moment magnitudes M-w of 8.6 to >9. Sufficient strain has accumulated along this portion of the Himalayan arc during the roughly 800years since the 1146-1256A.D. earthquake to produce another earthquake displacement of similar size. Plain Language Summary The densely populated country of Nepal sits above the Himalayan Frontal Thrust fault. It is repeated displacements on this fault that are responsible for the uplift of the Himalaya mountains and considered capable of producing great earthquakes. Here we excavate a trench across the fault to show a great earthquake occurred 1146 -1256 AD in eastern Nepal. It has been a sufficiently long time since then that stresses have accumulated to a level capable of producing another such great earthquake
Determinants of the corporate decision to disclose stakeholders' reports in France
No full textThis study develops and empirically tests a model of the corporate decision to disclose stakeholders' report by French firms. The related literature is then reviewed. The first section identifies the factors influencing the decision to disclose stakeholders' reports. The factors examined have been broken down into three categories: corporate characteristics, external factors and internal factors.In the second section, variables are then defined before a presentation of the empirical tests. This study hypothesises that the decision to disclose stakeholders' reports is correlated with the size, the reputation of industry, the financial performance, the salience of stakeholders and the degree of internationalisation of the firm's activity. Finally, a summary and a conclusion are presented. The results show that the salience of stakeholders and the reputation of the industry are the most important factors and the degree of internationalisation of the firms has no influence on this decision. We interpret this finding as consistent with stakeholder theory.Stakeholder theory, stakeholders' report, corporate characteristics, external factors, stakeholders
